Specialized Shield Support
1. The special cover mine support bracket adopts a buffer structure design, which can absorb the impact energy of the sudden pressure of the roof and prevent the bracket from deforming.
2. The special cover mine support bracket can flexibly adjust the support range according to the width of the tunnel to meet the needs of different sections.
3. The special cover mine support bracket can be moved along the roof by manual or remote control.

Introduction of mine support bracket:
The special cover mine support bracket is a kind of equipment specially used for the roof support of the tunnel withdrawing frame in the mining working face. Usually, each mining working face is equipped with two sets of this bracket to ensure the stability of the roof during the withdrawal. The equipment can be moved along the roof track by manual control or remote control, and the front frame and the rear frame alternately support to achieve cross-stepping advancement, effectively avoiding the problem of roof collapse caused by the forward movement of the bracket. The mine support bracket is also connected to a traction steering platform to speed up the equipment withdrawal speed through relative movement and improve work efficiency.

Features of mine underground support bracket:
1. The mine underground sport bracket has a large supporting capacity, the top beam is in good stress state, and the top cutting performance is strong.
2. The mine underground support bracket has a protective beam, which can effectively separate the working area and the goaf to prevent gangue from rushing in.
3. The mine underground support bracket has good stability and a large working space, which is convenient for ventilation and pedestrians.
4. The structure of the mine shield bracket is relatively complex, the amount of steel used is large, and the cost is high.
5. The contact pressure between the mine shield bracket and the top and bottom plates is relatively uniform, the maximum contact pressure is relatively small, and it has high stability.
Application of mine shield bracket:
1. Coal pillar-free mining: The side support body and the support are carried in coordination, and the dynamic pressure-releasing design adapts to the settlement of the roof of the goaf.
2. Top coal caving working face: Maintain the rear coal caving space to prevent the impact of gangue on the reinforced structure.
3. Emergency rescue project: Rapid support in the caving area to quickly build a safe passage, and the modular lightweight design is easy to transport.
4. Deep mining application: impact-resistant support, high-temperature resistant hydraulic system.
